Application filed February 24, 1908. Serial No. 417,526.

To all whom it may concern:

lie it known that I, (humans TUCKFIELD, a subject of the King of Great Britain, residing at 4 Thames View, East Molesey, Surrey, England, have invented a new and useful Improved Engine, ofwhich the following is a specification.

' This invention relates to an engine or motor adapted to be driven by steam, gas or other motive fluid of the kind wherein a drunken disk operated by a series of pistons on one side thereof, is employed to drive a shaft through the medium of an inclined disk in frictional contact I with the said drunken disk either'directly or through the medium of anti-friction balls or rollers and has for its object to obviate or counteract the longitudinal thrust on the shaft due to the action of the drunken disk on the inclined disk. According to the invention a second series of pistons and a second inclined disk are arranged in positions, relatively with the drunken disk, opposite to those of the series of pistons and inclined disk above mentioned.

In the accompanying drawing :'Figure 1 is a sectional elevation of an explosion engine embodying the im rovements. Fig. 2 1s a sectional end view 0 the same and Fig. 3 is a view of a detail. Fig. 4 is a sectional view of a modified detail.

a, a are the power cylinders of the engine which are single actmg and arranged in pairs with their members in alinement and their axes parallel with the shaft b to be driven, the said pairs of cylinders being arranged around the said shaft at the same distance therefrom and at equal distances apart.

0, c are the pistons which are of the trunk type working within the cylinders a, a, those of each pair of alined cylinders being conneeted together by. a rod d.

e is the drunken disk arranged at an angle to the shaft 6 and connected by universal joints to the rods cl, d by arms 0, c on the said disk, the said joints comprising blocks f, f having holes to fit and turn upon the said arms and pivoted by trunnions f, fto the rods cl, cl.

g, g are the disks or plates fixed to the shaft 7) at the same angle as the disk 0 and between which plates is located the said disk 0 the movement of which is imparted to the disks g, g preferably through the medium of anti-friction rollers g, g or the like.

By the described arrangement will be understood that the reciprocating movement of the pistons e, within the cylinders (t, a will cause the disk 0 to rotate the shaft 7), the employment of the four pairs of cylinders around the shaft 7) obviating any dead centers. i

The disks 9, y are preferably formed hemispherical to prevent fanning action.

71, i are respectively the inlet and exhaust valves for each cylinder, the said valves being operated by a cam disk loose on a sleeve k, the said disk being designed to rotatc at half the speed of the shaft I) through the medium of spur teeth Z on the sleeve, idle pinions m and internal gear teeth a on the disk. Each disk j of which only one is shown in the drawing carries cam-pieces 0, p for operating the valves 71, and 1' respectively and in order that the engine may be reversed the disk j is arranged to'bc moved relatively with the valves. For this purpose the cam pieces 0, 0 are carried loosely in slots g, g as shown clearly in Fig. 3, so that when rotated in either direction the said cam pieces are driven by contact with opposite ends of the slots, the said cam-pieces being moved in the slots by the resistance of the valve stems. For moving each cam disk 7' relatively with the valves it is advantageous to employ a sleeve r arranged to slide on a feather key on the shaft b and provided with a quick threaded screw 0* engaging a corresponding thread on the interior of the sleeve is so that when the sleeve 1" is moved longitudinally on the shaft 6, for instance, by a lever s the cam disk j will be rotated relatively with the valves and the engine reversed. When either steam, compress air or the like is used as the motive fluid for the engine, the cam disk j is connected directly to the sleeve in, for instance by ke s 7; as'shown in Fig. 4 so as to be driven at t e same speed as the shaft 6.

When using the improved engine for driving motor vehicles, it is preferably placed across the car with a pulley at each end of the shaft connected directly to the wheels by means ofa belt or chain, the pulleys being of the free wheel type with means for locking them to the shaft when backing the vehicle, or when large cylinders are employed the driving wheels may be directly attached to the shaft which would then form the axle of the said wheels, the latter being of the free wheel type but capable of being when backing the veformed, I declare that what I claim is i l. in a multiple cylinder engine, the combination of a driving shaft, cylinder pistons arranged in pairs in alineinent, a pair of inclined disks fixed to the said shaft so as to rotate therewith and an inclined nonrotating disk arranged between the rotating disks and connected to and between each pair of the pistons, substantially as described.

2. In a multiple cylinder engine, the c0mbination of a driving shaft, cylinder pistons arranged in pairs in alineinent, a. pair of inclined disks fixed to said shaft so as'to rotate therewith, an inclined non-rotating disk arranged between the rotating disks and universal joints connecting the said nonrotating disk to and between each pair of the pistons, substantially as described.

3. Tn a multiple cylinder engine, the combination of a driving shaft, cylinder pistons arranged in pairs in alinement, a pair of inclined disks fixed to said shaft so as to rotate therewith, an inclined non-rotating disk arranged between rotating disks and connected to and betweenveach pair of the pistons, inlet and exhaust valves for each cylinder, a disk cam carried upon the driving shaft for operating the said valves and means for moving the said disk cam relatively with the shaft to reverse the engine, substantially as described.

4. In a multiple cylinder engine, the combination of a driving shaft, cylinder pistons arranged in pairs in alinement, a pair of inclined disks fixed to said shaft so as to rotate therewith, an inclined non-rotating disk arranged between the rotating disks and connected to and between each pair of the pistons, inlet and exhaust valves for each cylinder, a disk cam carried upon the driving shaft for operating said valves, a screw threaded sleeve operatively connected with the disk cam and a screw threaded sleeve engaging said sleeve and keyed to the driving shaft but free to slide longitudinally thereon, substantially as described.
